Pollen itself is not the male gamete. [4] It is a gametophyte, something that could be considered an entire organism, which then produces the male gamete.Each pollen grain contains vegetative (non-reproductive) cells (only a single cell in most flowering plants but several in other seed plants) and a generative (reproductive) cell.
A pollen count is a measurement of the number of pollen grains in a given volume of air. Pollen counts, and forecasts of pollen conditions, are routinely produced and reported to the public because high aerial pollen concentration is associated with increased rates of allergic reaction for those with conditions such as hay fever and asthma .
A food allergy is an abnormal immune response to food.The symptoms of the allergic reaction may range from mild to severe. They may include itchiness, swelling of the tongue, vomiting, diarrhea, hives, trouble breathing, or low blood pressure.
Food processing is the transformation of agricultural products into food, or of one form of food into other forms. Food processing takes many forms, from grinding grain into raw flour , home cooking , and complex industrial methods used in the making of convenience foods .
Also free from FDA’s 9 major food allergens: No, contains milk and eggs, as well as soy lecithin (check with an allergist, though—many with soybean allergies can eat soy lecithin). Kids with ...
An allergen is an otherwise harmless substance that triggers an allergic reaction in sensitive individuals by stimulating an immune response.. In technical terms, an allergen is an antigen that is capable of stimulating a type-I hypersensitivity reaction in atopic individuals through immunoglobulin E (IgE) responses. [1]
Dry pollen, is a food source for bees, which may contain 16–30% protein, 1–10% fat, 1–7% starch, many vitamins, some micro nutrients, and possibly a little sugar. The protein source needed for rearing one worker bee from larval to adult stage requires approximately 120 to 145 mg of pollen.
Food allergy and variable IgE response to food substances has been observed in some patients which implies role of hypersensitive response in pathogenesis. Many patients indeed have history of other atopic conditions like eczema , asthma etc.
